it is useful to know which materials are electrical conductors so if you wanted to make an electric current you could. For example is you where making a circuit you would need to know which materials you could use that would conduct electricity.
or if there is something stuck in a power point you know what material to use to get it out without getting electrocuted
We need electricity to be conducted in some cases and insulated in others. For example, wires are made of copper due to its low resistance of electricity, allowing less energy to be used but at the same time passed to an appliance. Wire coverings are made of plastics or rubber to protect us from getting a shock when we touch it even when electricity is conducted in the wire.
Classifying matter into conductors and insulators helps us understand how different materials interact with electricity. Conductors allow electricity to flow easily, making them useful for wiring and electronic components, while insulators prevent the flow of electricity, which is important for safety and preventing short circuits. This classification is crucial for designing and using electrical systems effectively.
Materials that allow electricity to flow through them are called conductors. Common examples of conductors include metals such as copper, aluminum, and silver. These materials have loosely bound electrons that are free to move and carry electric charge.
Conductors allow the flow of electricity due to the presence of free electrons, while insulators inhibit electron flow. Conductors often have low resistance, while insulators have high resistance to the flow of electricity. Materials such as metals are good conductors, while materials such as rubber are good insulators.
Electricity can flow in the conductor becourse the conductor is made up by electrons. When the wire is connected to the source, these electrons do vibrate and caurse collision among themself. This collision caurse electricity to flow throw the conductor/wire.
Normally, materials which are good conductors of electricity are also good conductors of heat. This is because both electrical conductivity and heat conductivity is enhanced by mobile electrons, thus making metals both good electrical conductors and good heat conductors. However, I do not know if there might be an exception...

from wiedemann franz law we know that thermal conductivity/electrical conductivity=constant that is sigma inv. proportional to k thus a material having large electrical conductivity has low thermal conductivity and moreover we know R=pL/A p=RA/L 1/P=L/RA i.e lower area means greater conductivity(electrical) and lower thermal conductivity

In many cases, yes, it is necessary to measure the conductivity of a material. We need to know how well materials conduct electricity, particularly if these materials are used in the construction of anything electrical or electronic. We need to know what we can use around electrical circuits that won't conduct well, and we need to find things to make up that circuit that are good conductors. Simple, easy to understand.
I dont even know Lool

Viscosity is an important parameter for materials in industry; it is useful to know the flow behavior.

Superconductors are materials that offer no electrical resistance whatsoever but the highest temperature any known superconductor can be while retaining its conductive properties is -181 degrees Celsius, making them an extremely impractical and expensive material for most purposes. As far as I know the most conductive material at room temperature is pure silver, which is slightly more conductive then pure copper and 50% more conductive then pure gold. Copper and gold are both used commonly for conduction however because copper is much cheaper then silver and nearly as conductive, and gold is more resistant to corrosion then either silver or copper despite its reduced capacity for electrical conduction.
Bad conductors of electricity are materials that do not easily allow the flow of electric current. They have high resistance to the movement of electrons, resulting in very low conductivity. Materials like rubber, glass, and plastic are considered bad conductors of electricity.
